Unboxing values from julia OrderedDict in Rust

[jeenou]

Hello again,

I would like to know if there is some easy way to unbox values from julia OrderedDict type of parameter. I have a function in julia that returns OrderedDict where I have data in timeseries format and I would like to use that data in rust. What would be the best way to do that and can I have an example?

The definition of OrderedDict is

mutable struct OrderedDict{K,V} <: AbstractDict{K,V}
    slots::Array{Int32,1}
    keys::Array{K,1}
    vals::Array{V,1}
    ndel::Int
    maxprobe::Int
    dirty::Bool
end

Which should map to

#[repr(C)]
struct OrderedDict<'scope, 'data> {
    slots: Option<ArrayRef<'scope, 'data>>,
    keys: Option<ArrayRef<'scope, 'data>>,
    vals: Option<ArrayRef<'scope, 'data>>,
    ndel: isize,
    maxprobe: isize,
    dirty: Bool,
}

in Rust. In practice, though, I think it's easier to use a field accessor here to access the particular field you're interested in. In either case you depend on implementation details of OrderedDict, though, but directly accessing the field should perform significantly better than calling Julia functions to access it.
